CVE-2026-88859 (GCVE-0-2026-88859)

Vulnerability from cvelistv5 – Published: 2026-09-10 11:24 – Updated: 2026-09-10 15:04

Title

Evolution: evolution: javascript execution via spoofed vcard control bypasses mail script-markup restriction

Summary

A flaw was found in Evolution. A remote attacker can exploit this vulnerability by sending a specially crafted HTML email containing a spoofed vCard control. When a victim clicks on this control, Evolution's trusted JavaScript handler incorrectly assigns an attacker-controlled JavaScript URL to an iframe's source. This action leads to arbitrary JavaScript execution within the mail-viewing context, effectively bypassing the security measures designed to prevent script execution in email content.

Severity
